Abstract

Combined modality hover drift cueing methods, systems and computer readable media are disclosed. For example, some implementations can include a system comprising one or more sensors, and a combined modality hover drift cueing controller coupled to the one or more sensors and configured to determine hover drift and to control a plurality of indicators in response to determined hover drift. The system can also include a mode selector coupled to the combined modality hover drift cueing controller and configured to provide an indication of mode selection between one of a first mode, a second mode and a third mode, wherein the first mode is a combined modality mode. The system can further include a peripheral vision hover drift indicator coupled to the controller and mounted on an inside surface of an aircraft cockpit, and a tactile feedback indicator coupled to the controller.

Claims

1-7. -7. (canceled)

8. A method comprising:

receiving, at a processor, vehicle position information from one or more sensors disposed on the vehicle;

determining, at the processor, position drift based on the received vehicle position information; and

controlling, with the processor, a peripheral vision position drift indicator and a tactile feedback position drift indicator based on the determined position drift.

9. The method of claim 8, wherein the vehicle includes one of a land vehicle, a surface water vessel, an underwater vessel, an aircraft and a spacecraft.

10. The method of claim 8, wherein the peripheral vision position drift indicator includes a first position drift indicator and a second position drift indicator.

11. The method of claim 10, wherein the peripheral vision hover drift indicator further comprises a third position drift indicator coupled to the processor.

12. The method of claim 10, wherein the first position drift indicator is configured to indicate fore/aft drift.

13. The method of claim 10, wherein the second position drift indicator is configured to indicate lateral drift.

14. The method of claim 12, wherein the first position drift indicator is mounted on a doorframe of the vehicle adjacent an operator'"'"'s seat so as to be visible in a peripheral vision field of the operator.

15. The method of claim 13, wherein the second position drift indicator is mounted adjacent to a central instrument panel of the vehicle so as to be visible in a peripheral vision field of the operator.

16. A nontransitory computer readable medium having stored thereon software instructions that, when executed, cause a processor to perform operations including:

receiving, at a processor, aircraft position information from one or more sensors disposed on the aircraft;

determining, at the processor, hover drift based on the received aircraft position information; and

controlling, with the processor, a peripheral vision hover drift indicator and a tactile feedback hover drift indicator based on the determined hover drift.

17. The nontransitory computer readable medium of claim 16, wherein the one or more sensors include one or more of a radar altimeter, an air data system, an inertial navigation system, a traffic alert and collision avoidance system, an Enhanced Ground Proximity Warning System (EGPWS)/Controlled Flight Into Terrain (CFIT) system, a digital map, a terrain database, a Global Positioning System (GPS) receiver, a Differential Global Positioning System (DGPS) receiver, a microwave radar, a forward looking infrared (FLIR) camera, and/or a video camera.

18. The nontransitory computer readable medium of claim 16, wherein the peripheral vision hover drift indicator includes a first hover drift indicator and a second hover drift indicator.

19. The nontransitory computer readable medium of claim 18, wherein the first hover drift indicator is configured to indicate fore/aft drift and is mounted on a door frame of the aircraft adjacent a pilot'"'"'s seat so as to be visible in a peripheral vision field of the pilot.

20. The nontransitory computer readable medium of claim 18, wherein the second hover drift indicator is configured to indicate lateral drift and is mounted adjacent to a central instrument panel of the aircraft so as to be visible in a peripheral vision field of the pilot.
